Added Class of device support for BLE, updated the ESP32 makemenu config to use magic enum(optional) and resolved emum clash when using Arduino IOT - #438
Conversation
…s for using magic enum and Arduino IOT support
Added installation instructions for PlatformIO and updated content.
Added information about compatibility with ArduinoIoT libraries for Alexa and Google integration.
Removed installation instructions and related details from README.
📝 WalkthroughWalkthroughArrr, this change adds Class of Device encoding, decoding, and advertising support. It adds optional Arduino IoT aliases and magic-enum output. It also updates ESP-IDF configuration references, characteristic APIs, advertising validation, server reporting, and README content. ChangesNimBLE support updates
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🟠 High · up to The current changes alter BLE service lifecycle and advertising behavior, but still contain compile-breaking configurations, service registration and notification failures, and malformed advertisement-length handling that can leave clients with stale databases or invalid payloads. These high-impact correctness and integration issues should be fixed before merging. Sequence Diagram(s)sequenceDiagram

Inline comments:
In `@src/NimBLELocalValueAttribute.h`:
- Around line 36-46: Update repository examples and documentation to reference
NIMBLE_PROPERTY::BLE_READ and NIMBLE_PROPERTY::BLE_WRITE when
CONFIG_NIMBLE_USING_ARDUINO_IOT is enabled, matching the enum names in
NIMBLELocalValueAttribute. Alternatively, add an intentional public
compatibility layer for NIMBLE_PROPERTY::READ and NIMBLE_PROPERTY::WRITE; do not
leave references that fail after the compatibility macros are undefined.
- Line 110: Update the initLen default in the affected attribute declaration to
use MYNEWT_VAL(NIMBLE_CPP_ATT_VALUE_INIT_LENGTH) instead of
CONFIG_NIMBLE_CPP_ATT_VALUE_INIT_LENGTH, matching the portable fallback used by
NimBLEAttValue.h and NimBLEValueAttribute.h.
In `@src/NimBLEServer.cpp`:
- Around line 98-99: In the NIMBLE_LOGI call, correct the diagnostic message
text from “serice” to “service” while leaving the surrounding logging behavior
and arguments unchanged.
- Around line 194-196: Update the preprocessor guard surrounding
ble_gatts_show_local() to use MYNEWT_VAL(NIMBLE_CPP_LOG_LEVEL) instead of
CONFIG_NIMBLE_CPP_LOG_LEVEL, preserving the level threshold so non-IDF builds
honor their configured debug logging level.
In `@src/NimBLEServer.h`:
- Around line 88-89: Update NimBLEServer::toString() to be const in both its
declaration and definition, and construct the service-count text using
std::to_string(m_svcVec.size()) rather than the current pointer-arithmetic
expression.
Apply the same fix in `@src/NimBLEServer.cpp` around lines 751 - 754: The
implementation contains the matching pointer-arithmetic and
discarded-string-expression defects.
In `@src/NimClassOfDeviceType.cpp`:
- Around line 180-189: Remove the Class of Device LE advertising payload
generated by makeATT_Payload_CodeClassOfDevice, including its AD type 0x0D
setters and related use sites; do not replace it with another LE advertising
field unless an existing supported classification mechanism is already defined.
- Around line 80-88: Update the Class of Device formatting in the relevant
conversion function to use regular enum_name for major_device_class_t and
non-bitmask minor enum values, preventing bitwise decomposition of ordinary
codes. Retain enum_flags_name only for service_class_t and
imaging_minor_class_t, and preserve the existing miscellaneous-major fallback.
In `@src/NimClassOfDeviceType.h`:
- Around line 98-99: Update the enum values for COD_MINOR_LAN_UTIL_67_TO_83_PERC
and COD_MINOR_LAN_UTIL_83_TO_99_PERC to 0x28 and 0x30 respectively, preserving
their existing utilization labels.
- Line 5: Remove the unconditional WString.h include from
NimClassOfDeviceType.h, since its declarations do not use Arduino String types;
keep the header compatible with standalone ESP-IDF builds and only add an
Arduino-specific guard if an Arduino-only API requires it.

Added Class of device support for BLE all devices now supported
Updated the ESP32 makemenu config to use magic enum(optional) so that better logging can be done for class of device support . The support is non breaking if no magic_enum lib is present code will still compile and work.
Set the define NIMBLE_USE_MAGIC_ENUM to enable linking with magic_enum lib (https://github.com/Neargye/magic_enum) for detailed logs on class of device else the code executes as old
Set the define NIMBLE_USING_ARDUINO_IOT to enable enum clash resolution else the code execuutes as old
